Ethernet and/or WiFi support to access Audio Files from a Network Share Optional

I would like the final version of this project should be a dedicated PCB mounting all the components, avoiding to use the official Arduino board and Shields...

I already have in my mind some ideas on how to design the whole system, but I am really stuck with the MP3 Decoder chip: I've seen the "mighty" bu94605akv (http://www.rohm.com/products/databook/audio/pdf/bu94605akv-e.pdf), which seems to be able to do the most of the job on his own and leaving to the Arduino just the "outer world" interface, and the "dear old" VS1053b (http://www.vlsi.fi/en/products/vs1053.html), which seems to need a bit more work on the ATMega328 but is widely known and supported because is used on several MP3 Shields.

The main issue in thinking about using one of those two MP3 decoder is that I am totally unable to solder SMD-like component, so I would prefer something that comes in a different package (dual inline would be great...)

or even maybe you should not try this on an arduino, why don't you look into raspberrypi, you'll be able to do all what you want. Now that I think of it I have a machine with such a case running linux with mythtv doing all that (with lcd, IR and SPDIF and upnp ans smb mounts)

have you conisdered the http://www.vlsi.fi/en/products/vs1053.html vs1053 it can be bought on ebay for 7 dollars with free shipping or there is the newer one the vs1063 http://www.vlsi.fi/en/products/vs1063.html but no distributes or ebay seem to carry it.

Yes you are right about the breadboard this will involve the a breadboard to prototype it however about the dip adapter instead of an adapter it appears that the best value for money right now would be to purchase a breakout board on ebay they can be had for 13 dollars just by searching VS1053 and sorting by price lowest to highest and scrolling down a bit then click on the development board or here is the cheapest one but still good quality http://www.ebay.com/itm/MP3-Module-Development-Board-AMS1117-Recoder-For-VS1053-/280794429816?pt=LH_DefaultDomain_0&hash=item4160a6f978 I believe it is actually cheaper to buy the development kit than just buying a dip adapter and as for an i2s DAC the ic chip has a built in one I personally would just do with that as it would be simpler however if you do want to use an external one after a quick search I would recommend this:http://search.digikey.com/us/en/products/PCM1753DBQR/296-26301-1-ND/2254953As it is under 3 dollars for one however you will have to buy another adapter which are on ebay for 2 dollars http://www.ebay.com/itm/SSOP-16-to-DIP-16-pin-Adapter-PCB-SMD-Convert-/140598901069?pt=LH_DefaultDomain_0&hash=item20bc58f94dand here is an awesome web page about how to use it:http://kalum.posterous.com/50759184and you need an lcd here is 16x2 character display for 3 dollarshttp://www.ebay.com/itm/New-1602-16x2-HD44780-Character-LCD-Display-Module-LCM-blue-blacklight-/140738656157?pt=LH_DefaultDomain_0&hash=item20c4ad779dand now though after looking all this up and think about the cost and I know I am not the first person to say thisBut the thing is it will cost alot more to order all the stuff and make the pcb board and all the time involved to me appears not to be worth it I personally would just buy an mp3 player but if you have an idea that can't be done with a normal mp3 player (I do which is why I am interested in audio playback with the arduino) then this is something that you should consider however what you want do except maybe the

which maybe a product does support some of those things without my knowledge.And also did you edit your post to include the vs1053 or did I just miss that and made post that suggested the same thing that you did?

That's a good point but I was tempted to do it on myself rather than relying on a shield...

I am an IT System and Network Engineer... My living room is already fulfilled with any kind of linux boxes for movies and so on... but I really would love to go back 15years and play a bit with electronics...

yep! good pick but it's smd... I am not able to solder it on my pcb...
